The Apollo's transport, manufactured by Sanyo, is compliantly suspended from the upper portion of Rega's standard chassis of cast aluminum alloy. The D/A converter is Wolfson's top-of-the-line WM8740, a dual-differential chip that operates in sigma-delta mode and supports word lengths of up to 24 bits. The output section, which is said to apply class-A amplification to a digital source component in an entirely new way, is Rega's own design.
